First: Any app backing up sensitive information via a cloud, should instantly be uninstalled and never be used again. That's a horrible approach.
The whole use of a backup is to have private keys stored in a safe environment. If those 'backups' of this app do not contain private keys, they aren't real backups.
I heavily suspect the App to be malicious. You might try to generate a new wallet and see if you can somehow export a seed/private key.
If you can't, the wallet definitely is scam.
In case of the wallet being malicious, make sure to uninstall it and make an anti virus scan of your mobile phone. Your coins are lost in this case, unfortunately.
